Only a reverse of the
original image data can be displayed on the opposing side with conventional double-sided LCDs. With Samsung's
double-gate, TFT design, the LCD features two gates which operate each pixel
instead of just one. This is what allows Samsung to produce two independent
images. Amorphous Silicon Gate (ASG) technology also allows Samsung to manage
the increase in TFT gates without a subsequent increase in driver ICs.

One backlight is shared between the two LCDs. The front LCD
is transmissive and the opposing screen is reflective (which allows it to
capture some of the light from the main screen). In its current form, Samsung's
double-sided LCD is 2.6mm thick with a QVGA resolution. Brightness levels
register at 250 nits for the front panel and 100 nits for the back panel.

"Our new double-sided mobile display underscores
Samsung's commitment to equip our customers with advanced display technology
that accelerates the trend toward slimmer mobile products. We anticipate high
demand when we commence mass production in the first half of 2007," said
Samsung Executive Vice President Yun Jin-hyuk.
